To all whom t ma?) concern.'

Be it known that we, OSCAR vand CHARLES A. RINEHART, citizens of the UnitediStates', residing in the city of St. Louis and State of Missouri, have invented -a new and useful Improvement in Doorlocks, of which the following is a vspecification.

This invention relates to locks and latches. l0 lt has more particularly to do with door locks and is especially well adapted for application to and use upon the doors of automobile bodies and the'like, but'withont being necessarily limited to such application and use. A i

The principal object of the invention is to produce, in a lock of this character, a simple, dependable and durable structure, which is readily installed, permits the door to be closed without slamming, releases easilyy to permit the door to be opened, at will, yet

holds securely against accidental opening,

and prevents rattling. and saggingof the door. Other important objects and advan- 15 tages tobe attained will more fully appear in the following description.

Thel invention consists in the parts and.'V in the combinations and arrangements of parts as hereinafter set forth andpointed out with particularity in the appended claims.

In the accompanying drawings forming part of this specification and illustratinga .practical adaptation of the inventionff- Figure 1 is a fragmentary View, 'inelevation, of the adjacent' meeting portions of the door and sideT of an ordinary automobile body, with parts of the upholstery removed to illustrate the installation of a lock ac- 40 cording to the present invention;

f Referring now to the drawings, the numeral 1 'designates the door andthe numerals 2' and- 3, respectively, the adjacent side portions of an ordinary automobile body. The door, is hin ed, ,asl at 4, inthe usual mam ner, so as .to swing outward in opening.' As shown (see Figure 2), the meeting edges of the door and the`door post 5 are bevelled cor-- respondingly, as at 6. The inner face of the door (see Figure 1) is provided with the usualupholstery panel 7, part of which vlatter is :removed to yexpose-the top rail 8- and end 'rail 9 of the frame of the door, to which rail members the lock body vplate 10 is attached by the screws 11. In'this connection, it may be here stated that the lock body plater structure and the manner -in which it is vfastened to the door serves as a gusset plate or reinforcement of the doorframe and obviates .the necessity for providing the door frame with the', usual supplemental supporting block or frame member for the lock, and at the same time 1t min1- mizes the cutting away or mortising of the door Uframe to accommodate'the lock mechanism.

' A part of the upholsteryv 12 of the body of the automobile 1s also Shown removed'to expose the door post 5 in the. region where len the keeper bracket 13 for the lock is attached. The keeper for the lock comprises essentially a suitable bracket member' 13, which, as shown, is preferably an angle-plate provided with apertures 14 1n one of its flanges (see Figure 14) for the reception of screwsor bolts 15 (see Figure 5) by which it isattached to the door post. Preferably, this flange is countersunk into the door post so that the outer face of the flan e is substantially flush with the face of e door post. On the other flange of this bracket is a stud 16 having an annular groove 17 and a tapered end portion 18.

The llock body plate 10 is provided with an' aperture 19 to receive said stud 16 when the door is closed. This aperture is of a diameter to receive the stud preferably with a rather snug fit, particularly the cylindrical base portion of the stud. That is to say, with practically little or no play laterallyof the stud,

On the body plate 10 is a 'supplemental plate 20 having an aperture ofthe same size as and registering with the aperture 19. This plate 20, which is provided 'principally as a reinforcement, may be attached to the body plate 10 in any desirable manner but, preferably, it is provided at three places, as shown, with 1u s 21 which are turned at right angles to t 1e body portion of the plate and are of a length sufficient to enter apertures provided therefor in the body plate 10 and in which apertures said lugs are riveted securely.

' The supplemental plate 2O has a marginal flan e 22 which abuts a marginal flange 23 of the lock body plate 10, said flange 23 being provided for attachment to the end of the door and said flange 22 affording a rein.- ;forcement for relieving the flange 23 of thrusts and strains. This supplemental plate 20 is further provided `With an aperture 24 registering vwith a like aperture in the lock body plate 10 to receive and have riveted or otherwise fastened therein the reduced end portion of a shouldered pivot stud 25 for a rocking latch member 26 whose end portion Works in a slot 27 provided therefor'in said flange 22 of the supplemental plate 2Q (see Figures Band 6).

` The latch member 26 has an angular en.-

,tensfion 2S, the end portion of which is turned up to constitute a lug 29, one edge4 .'portion of which latter is bevelled Orcinclined, as at 30, t afford a fcam face. The opposite edge portion of the lug 29-is provided with a notch 31 to .receive the endpor tion of one leg 32 of a spring element 33 whose middle portion is looped and coiled,

'as at 34, and whosgJ other leg 35 is hooked.

- as at'36, and engaged in. a notch 37 in the edge of a lug 38 which is turned up from the supplemental plate 20.

' The looped middle portion 34 of the'spring ing' and The spring 33 is constantly under tension` and, its legs 32 and 35 acting in opposed relation upon the respective lugs 25) and 38,

`holds the latch member 26 yieldably in normal position with its end portion against the end of the slot 27 of the flange 22 of the reinforcing plate 20/and also restores it vto such normal position afterjeach operationl thereof When in normal position, the edge portion of the member 26 crosses the aper- `ture 19 chord-wise (see Figure 3) so as to entery the roove 17 of the keeper stud 16 when the atter has entered the aperture 19 as the door is closed. In this connection, it may be here stated that, as the tapered head 18 of the stud ente-rs the aperture 19, the latch member 26 is rocked to clear said aperture and as the groove 1.7 is brought beyond the inner face ofthe plate 20, the latch membep snaps into said groove by the action of the spring 33. The relative width of said groove 17 and thickness of the latch member isv such that said latch member readily enters said groove, more or less play being provided for this purpose as may be desired.

Pivoted between ears 40, struck up from the body plate 10, as shown in Figures 3, 4

and 6, 1s an operating lever 41, at one end o f which is an angular projection 42 normally engagin the cam face 30 of the extension 28 of t e latch member 26. At the opposite end Jof the lever 41 is a push-button 43 which projects normally through an open- .-1

ing 44 in thebody plate 10. As shown, this push-'button is cupped or has its marginal portion flanged, as at 45, and the opening 44 also has a surrounding flange 46 the upper portionp of which,47, is preferably higher p than ythe remainder, while the lower portion is cut away or slotted, as at 48, to provide "clearance forthe lever 41.

The flange 46, which is provided to afford a guard about the opening 44, is preferably drawn up as an"integralvpart of the body7 plate 10, as shown, but, obviously, it may be 1 made as a separate piece and attachedto the 'body plate according to any usual or/ ap- .with the keeper stud 16 and clear of the aperture 19, this movement being arrested llt) by the latch member coming in contact with the end ofthe slot 2 7 opposite to that against which it is vnormally held yieldably by the spring 33.' Then the push-button is relieved of pressure thereon the spring 33, of course, restores to normal position the latch member and the several above noted parts which were operated therewith.

Mounted pivotally, as at 49, on an ear 50 struck up from the supplemental plate'20, is a second operating lever 5,1 having a bevelled end portion 52 to normally engage an` inclined cam projection 53 on. said latch member 26. The opposite end portion of this lever 51 is slotted, as at/54, to receive the'looped end portion 55 of a screw-r threaded connecting stem or member 56, which latter enters a screw-threaded bore 57 in the inner end portion of the stem 58 of a handle l59.

The handle stem 58 has its inner end portion 60 formed polygonal in cross sectioh,`

preferably square, as shown, and its middle portion 61 cylindrical` To accommodate this handle stem an escutcheon member 62 is provided with an outer collar 63 having .a cylindrical interior 64, to which the cylindrical port-ion 61 of the stem is slidably litted, and an inner collar 65 with an interior shape 66 which is a 'counterpart of the cross section Iof the portion 60 of the stem so asto afford an eas endwise -sliding movement of the handle, ut at the same time prevent the handle from turning independently of the escutcheon.

` .The escutcheon, as shown, has two :iper-- tures 67 for the reception of screws or bolts -68 by which it is attached to the outer face of the door. By this arrangement, the collar 65, which is preferably cylindrical externally, may be conveniently inserted through an opening vprovided therefor in the door and in .axlal alinement with the screw-threaded connecting'stem 56, so that the portion 60 of the handle stem may bev engaged with said connecting stem and the handle to ether with -the escutcheou turned to effect t e adjustment of the handle stem on the connecting stem, `When the adjust-l ment ,is finally effected the escutcheon is secured to the door by the screws or. bolts 68. After this is accomplished the handle 59 is prevented from rotating yet is permitted endwise movement in the escutcheon. rl` 'his adjustment takes care of doors of various thickness. v

To open the door from the outside it is i only vnecessary to pull the handle 59, which,

through the connection of the member56, rocks the operating lever 51; The lever- 51 whose end portion l5 2 vengages the cam pro-v jection 53 of the latch member 26 in turn,

rocks the latch member so as'to move it out of the oove 17 of the keeper stud 16 and clear o the opening`^19 in the lockbody plate, the'parts being restored to normal position by the spring 33, afterthe handle 59 is released, just as above pointed out 1n connection with the operation vof the latch which sup member by the actuation of the operating lever 41.

In practice the lock may be provided with only the operating lever '41 and its push-l button 43 or the lever 51 and its handle 59, or with/both of the operating mediums in the arrangement shown-as may be desired.

In any case, however, vthe operation of the mechanism of the lockrto open the door is easily effected with only one motion and that in the natural direction of opening the door. That is to say, the door is opened without 'irst rotating, twisting or rocking thehandle to release the'latch member from the keeper and necessitating torsional strain upon the hand of the operator to hold the lcatch in this released condition while pullalways bearing flatwise against the rein forcing plate 20. The stud being practically immovabletransversely in the opening 19 or with but very limited movement if any play is allowed at all in that direction, there 1s no probability ofthe latchmember working push or pull causing 'the door to and jarring out of the groove in the stud-Q' This structure .also permits the useA .of ak much. lighter and weaker. spring thanf. inf" the usual and more common typesof the locks heretofore in general use, particularly rnis those having latch-bolts slidable endwiseand' I l cammed back against a necessarily strong spring inclosing the door. A

The-re vis a still further advantage in the use of a lock of the character of the present invention in that it holds the door from sagging and-,pulling'end-wise away from` the door post. The stud of the keeper 'entering the aperturein the lock body plate, as .it does, affords an. interlocking engagement lports the door in every direction transverse y lor radially from the stud and the tapered headv of the stud insures lthe stud entering the aperture vin the'lookv body plate even thougl1 thev ldoorbe warped,I

sprung or sag, when open',r v so as to throw the aperture in the lock body plate considerably out of alinementwith the stud of the keeper.: "So, too, byhaving' the stud fit the aperture rather snugly, rattling of the door is materially eliminated. Also, thel keeper flange acts as a bumper or door stop: Furthermore, by jhavingthe. lock body plate 5 hanging on the stud-in opening and closing the door, as well as affording a sulicient bearing face to minimize wear of the metal surrounding the opening 19.

The arrangement of the operatinglevers v l0 is such that maximum power is obtained with minimum of Sfrictional resistance on the respective cani faces, and 'the arrangement is also such that oiling and lubricating is facilitated, inasmuch as it is only necessary to lappl oil on they lever 41 at a point just below tie push-button 43, through the opening 44, whereupon the oil will travel down the Llever 41 and follow on the latch member 26 and lever 51, thereby oiling and n lubricating the respective pivots.' and cam faces of said parts,

Obviously, the -stud 16 may be rectangular or of a cross section other than round or cylindrical as shown, and" the groove 17 u may extend only. 1transversely' across the upper part of the4 stud instead of annularly as shown. The entire structure and arrangement of theworking parts may also be considerably modified andchanged within the 3 spirit and scope of the invention as defined by the appended claims. The invention,
